COMB FOR WARPERS AND SLASHERS.

Specification of Letters Patent.

Application filed. March '7, 1910.

Patented Feb. 1st, 1911.

Serial No. 547,820.

To all whom "it may concern:

Be it known that I, ALoNzo E. Itnoanns, a citizen of the United States, and residentof I-Iopedale, county of IVorcester, State of Massachusetts, have invented an Improvement in Combs for \Varpers and Slashers, of which the following description, in connection with the accompanying drawing, is a specification, like characters on the drawing representing like parts.

This invention has for its object the production of an improved comb more particularly adapted for use in warpers and Slashers, whereby the dents of the warpguides are so constructed and arranged that when the comb is pushed up through the warp, termed striking in the upper ends of the dents will pass through the warp in such manner that the threads thereof will not become crossed.

In its general structure the comb forming my present invention is very similar to the device shown and described in United States Patent No. 818,560 granted to me April 24, 1906 insofar as relates to the bifurcation of the shank of the warp-guide to present two laterally separated dents lying in parallel planes, but in said patent the dents lie parallel to each other, so that the upper ends thereof are separated in a fore and aft direction. This construction is open to a practical objection in striking in for in that operation there is at times a. tendency of the threads to cross between two dents on a shank, instead of lying in substantial parallelism, such crossing of threads causing breakage as the warp travels through the dents of the comb.

In my present invention I maintain the two dents on a shank laterally separated and in parallel planes, but I cause the dents to converge toward their upper ends so that such upper ends are located side by side in substantial alinement lengthwise of the comb. By this arrangement there is no opportunity for the threads to become crossed between the two dents on a shank and the objectionable results due to such crossing are eliminated.

Figure l is a front elevation, and broken out, of a portion of a comb embodying my present invention; Fig. 2 is an enlarged transverse section on the line 2--2, Fig. 1, looking toward the right; Fig. 3 is a top plan View of a plurality of the improved warp-guides, showing the side by side arrangement of the upper ends of the dents; Fig. 4 is an enlarged perspective view of one of the warp-guides, detached, to clearly show the construction thereof.

In Figs. 1 and 2 the base 1 longitudinally recessed at 2 to receive the warp-guide shanks, the threaded adjusting shaft 3 controlling sleeves or nuts, as 4:; the pairs of coiled springs s, 8' attached at their ends to the nuts, the guides 5 extended through the springs, and the longitudinal slot 6 in the top of the comb-case, may be and are all substantially of well known construction and operate in usual manner. In its general features each warpguide is made very much as described in my patent, before referred to, the warp-guide consisting of an elongated and preferably flat shank an enlarged at its upper end at b and bifurcated or branched to present two upturned dents 0, (Z. The dent c is shown as a directcontinuation or prolongation of the shank and in the same plane, but the dent (Z is laterally offset from the shank by the bend e in the enlargement b by which the bases of the dents are connected with each other and with the shank. Preferably the warpguides are made of flat sheet metal, stamped or died out in any suitable manner, the bend e in the enlargement Z) bringing the two dents c and (Z into parallel but laterally separated planes, and the dent (Z is also inclined with relation to the dent 0, in my present invention, to bring the upper ends 0*, at opposite each other, as shown clearly in Figs. 2, 3 and 4. The bases of the dents o and (Z are not only separated laterally, but they are also separated in a fore-and-aft direction, as will be manifest, so that the pair of dents on each shank converge upwardly from their bases to their upper ends.

Referring to Fig. 3 it will be seen that by bringing the upper ends of the dents side by side they are alined in the direction of the length of the comb, in what may be termed a single bank or row, and when the dents of such a comb are pushed up through the warp the threads w, Fig. 3, can not become crossed between the dents on any shank, but must lie in substantial parallelism, separated by the series of dents.

By the novel construction herein shown and described I preserve all of the advantageous features of the warp-guide described in my prior patent, and at the same time I eliminate the objectionable feature thereof by causing the free or upper ends of the dents to lie side by side.

The warp-guide is very strong and durable, it is easily made, at a low cost, and it prevents crossing of the warpthreads in the operation of striking in Having fully described my invention, what I claim as new and desire to secure by Letters Patent is 1. In a comb of the class described, a series of warp-guides each comprising a shank having two separated dents laterally ofiset from each other and lying in parallel planes, said dents converging upwardly from their junction with the shank, to bring their upper ends side by side, in substantial alineinent lengthwise of the comb, and means to sustain and laterally position said warpguides.

2. As a new article of manufacture, a me tallic warp-guide for combs, comprising a flat shank bifurcated at its upper end to present two flat, separated dents laterally offset from each other and lying in parallel planes, the upper ends of said dents lying side by side in substantial alinement,

In testimony whereof, I have signed my name to this specification, in the presence of two subscribing witnesses.
